program specifications write a program that outputs a downwards facing arrow composed of a rectangle and a right triangle. arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width. note: this program is designed for incremental development. complete each step and submit for grading before starting the next step. only a portion of tests pass after each step but confirm progress. step 1 (3 pts). input the arrow base height (int) and width (int). draw a rectangle using asterisks (height x width). hint: use a nested loop in which the inner loop draws one row of *s, and the outer loop iterates a number of times equal to the height. submit for grading to confirm two tests pass.
